Referring tothe figures by characters of reference A'designates aportion of the chase sis or frame ofamotorvehicle on which is the frame being shown in:

mounted a motor B provided with the usual crankcase C constitutingv an -o'il reservoir. The forcepump used for elevating oil from the crankcase, to the variousparts of' the.

motor has not beenshown butthe oil usedIfor 7 this purpose is' directed by the pump-through a pipe 1 having aright angleextension 2 which extends through the dash. D .0f the vehicle. andto thelower end'ofa glass. tube or gage 3 carriedby thedashQ A valve 4 is OFDETBOI'I', MICHIGAN, A conro-r through apipe 5'with'asmallca'sing 6 in the lower portion; ofwhich is arranged an absorbentmaterial indicated at? (Figure 10) and which acts as aiwick. A screw 81is ad casing fi and hasga perforated head 9 at its lower end which bears upon'the mass ofabsorbent material? in the lower part ofthe casing. A'handle 10 is providedat the upper end offthe screw andby means thereof the head can be adjusted to Var'ythe pressure sid'eof thebolts; Another duct opens through the frame-A, as shown-at 22and int0 the pus- Y 1 1 then to the lower bolt bearing.

on the absorbent material and thereby c011- trol its efliciency as an absorbent medium.

Pipes 11 extend from the bottom portion of the casing 6 to distributing pipes 12 extendwhich, in. turn, is connected. by a. bolt 1.6 to one endofthe spring 1'? Each ofthesebolts.

has an oil d'uct 1'8therein provided with outlet openings whereby oil admitted to the duct is free to come into contact Withthebearing surfaces of the spring, link and bracket. A

pocket19-is formed-in the link between; the: ends thereof and contains an absorbent and.

porous material 20. Oil passages 21 extend longitudinally of'the link at the ends I of this pocket and communicate with. the ductsinsage in which the upper bolt 14 islocated. This passage 22 communicates with the distributing pipe 1'2'tlirough a branch pipe 23.

In the foregoing construction the" porous material at thedelivery end ofthelubricant supplypipe--that is; adjacent the-sliack-les is shown between two points to be lubricated; so that thelubricantfrom the supply line 12 Will flow to the upper bolt bearing of the shackle, then to the porous material 20,-and This is a proper and sufficient arrangement when the pressure of the lubricant in the-supply conduit is quite low, as when it is supplied by a gravity froman elevated container, as well also as'whenthe parts a re clbsely fitted so'that leakage is not likely to'occur at the bearing nothavingth'e porous materiahassoci'ated'with it; When, however, the lubricant is supplied under considerable pressure as-when-it comes from the lubricating system of the engine which. drivest'he vehicle or" from some other source ofi high" pressure, or when the bearings are less carefully fitted as is more frequently the: case, such porouscmateriali should be arrangedi immediately" adjacent" and ahead of each bearing to be lubricated, as is=thecase at the rearends of. the framemembers and rear springs in the embodiment of my'inven- 1510B illustrated. Insuch an arrangement the asupply of lubricant to. each hearing will be restrained to a degree by'the porous material through which itflows, and overfloWor-leakage of lubricant at. the bearings which: are

-lubricated,will= be prevented; Separate and distinct masses of porous material may, however, be' arranged adjacent each bearingeven when the pressure: of the lubricant supply is comparatively low; and as a matter-of fact better results will thereby ordinarily bersecured, especially after the: vehicle has been used for a time and the joints to be lubricated have become somewhat worn.

WVith the foregoing explanation, there is shown at other points in the vehicle structure lubricant boxes, one of which as indicated at 2a (Figs. 4 and 5) can be attached to the frame, as ordinarily, by a bolt 25 having an oilidu'ct 26 opening into 'thespring'27: mounted on the-bolt; In this box' is provided a pocket 28 containing an absorbent and porous material asindicated and which actsvto retard' theflow of oil, the. diictin theholt' '25 being, in communication with. pocket. This pocket is also incommuniicationwith the pipe 12 as is clearly indicatedin Figures 4 and 5.x Aspi ing; connection of difierent type is shown in Figures 8 and 9 where springs 37 at oppcsitessides oia; tramelban ofrtheschussis are supported at one end by bracket 30, shackles 32 and 33 being connected at opposite-ends-toth'e springsandthebolt. A duct 34 isex-tended longitudinally within the belt 31 and has outlets opening into the shackles and into the bracket 30, therebeing an additional duct 35=within the bracket and extending from a branch pipe '36 attached to the distributing pipei12i- The springs 37 are carrie'd by pivot bolts 38 mounted in the shackles and each ofthesepi vot bolts has a longitudinal d'uct- 39"openin'gto the outer'surfa'ee of the bolts; Theducts39 and 34 in'thebolt's'38 aud 31* respectively are-connected by'pipes'efi; A pocket 4 1 is fenned in=the upper portion of each shackle and contains an absorbent'material indicatedat'42 and ad'ucti 43 extend's- 'upwardlyto' this pocket from the adjacent duct 39. Thusitwill be; seen thatw-henfla lubricant is directed into the various ducts from the distributing-pipes 12, a portion thereof will be absorbedbv the'materia'l' 42- in each shackle" and will subsequently be supplied this absorbent" material downwardly through the'd'uct 453' to the various bearings.

In other words the absorbent material in the pocket providesa surplus supply' of lubricant. The bearing Mprovidtad for the radius ro'd 45 (Figures 6 and 7") has the usual bolt 46 extending from the radius rod and provided with a duct 47. This'duct communicates through a passage 48 witha pocket 49 containing an absorbent material indicated at 50 in Figure 7. Abranch pipe 51' extends to this pocket from the-di'stributing pipe 12. It'is to be understoodthat similar arrangements of absorbent containing pockets having ducts leadingtherefrom to bearings, can be provided wherever necessary, all of the pocketsbeing in communication with the-distributing? pipe 112. Thusit will be obvious thatwhen the motorisdn operation the force pump will: not only'lubricatethe'partsof the motor but a portion" of theelevated lubricant will be forced through the gage glass- 3' and into the: casing '6 from which it will flow downwardly through: the perfiorated head 9' and be absorbed by the material 7. Surplus and thence to the various wicks orabsorbent materials located at the different bearings v ous'parts of the automobile chassis, means from which the lubricant will be directed to the wearing surfacesof the bearings, in the manner hereinbefore pointed out. By ad usting the head 9 so as to increase or reduce the compression of the material 7, the efficiency of said material as an absorbent medium can be controlled. v

Where no force pump is provided for lubrieating and it becomes necessary to depend upon gravity, a casing 52 can be arranged above the level of the parts tobe lubricated, as shown in Figure 11. The casing 52 con tains an absorbent material 54 extending to a desired leveltherein and an'outlet pipe 54 having a valve 55 extends fromthe bottom of the casing to the distributing pipe. An overflow tube or chamber 56 isextended above the absorbent material and is in communica-. tion with the interior of the crankcase by means of a pipe 56 so that when lubricant is poured into the casing 52 and cannot all be absorbed by the material 54, the surplus can overflow into the tube or chamber 56 and enter the crankcase C.

In View of the premises it will be appreciated. that in the lubricating system wherein the invention consists the flow of lubricant to the several bearings (which is along a con duit which is always open) which would otherwise drip continuouslyfrom the bearings, is held back and restrained, and its flow regulated to a degree, by the masses of absorbent material at the several bearings and through which the lubricant flows. The supply of lubricant is always under some pressure and when, as in the preferred form of the invention, the lubricant is derived from the pressure lubricating system of the engine,

it is under a comparatively high pressure.

In that case and as hereinbefore appears, it is desirable that the pressure of the lubricant be reduced and regulatedflby causing it to flow through the casing 6 and theporous material under pressure therein, before itfiows into the distributing system of conduits leading to the various chassis bearings to be lubricated.
